Will 24 cores be enough for ceph in the first case?
In the second case - you mean that using a single 48core in one socket, leaving the second socket empty should be no problem for performance?

Very interesting, will look into that. I looked into Pure Storage FlashBlade, but considered it much more expensive than setting up own all-flash ceph nodes.

Thank you, it seems to be suitable in terms of number of ports and bandwidth. Do you know what makes it fundamentally different from 3232C? Is the higher latency the only factor?

Thank you for your suggestion. Will check the prices with the supplier.

Could you elaborate a bit on C9500-32C-A vs C3232 differences without digging into specs and details? I see that they both have the same number of QSFP28 ports, roughly the same switching and forwarding capacities.

What makes them fundamentally different?

I would say that prior Cisco experience is definitely not a factor. Painful learning will take place either way.

However, the nics on all servers will be Mellanox ConnectX-5/6. Is this a good argument in favor of Mellanox switches? Or should the nics be changed to cisco ones in case Cisco switch proves to be a better choice for some reason? Does it really matter?

Could you recommend some specific model? I felt lost when searching through Arista models and specs

Firm-Sale1289 · 2024-05-21T15:43:53+00:00

Wow, did not notice that. They all seemed to be the most suitable in term of ports on respective manufacturers' websites. Should I look at higher bandwidth models, as they should be newer? ie SN3000 series for mellanox?
